This paper describes a rich bivalve fauna from the Tubiphytes‐Limestone Member (Bithynian, early middle Anisian) of the Caerace Formation in North Dobrogea (Romania). We report 51 bivalve species, including 7 new species and 2 new genera: Atrina multicostata sp. nov., Pinna simionescui sp. nov., Chlamys (Praechlamys) prima sp. nov., Entolium reticulatum sp. nov., Scythentolium anisicum sp. nov., Romaniamya mahmudiaensis gen. et sp. nov. and Praedicerocardium vetulus gen. et sp. nov. The latter…

UPPER SPATHIAN TO BITHYNIAN (LOWER TO MIDDLE TRIASSIC) BRACHIOPODS FROM NORTH DOBROGEA (ROMANIA)
Brachiopods obtained from several Triassic localities in North Dobrogea, in Romania, are described. Upper Spathian and Aegean Hallstatt-type red limestones have been sampled in the Desli Caira…
New Triassic Aviculopectinoidea (Bivalvia), with notes on the taxonomic concept of the superfamily
Abstract. We describe two new genera of Triassic Aviculopectinoidea: Cristaflabellum n. gen., which is biconvex and has a strongly plicate shell, and Globodiscus n. gen., which is equiconvex and…
Paleoecology and paleobiogeography of the Cenomanian-Turonian bivalves from the Southern Galala Plateau (Eastern Desert, Egypt)
Abstract Fifty-three bivalve species from the Cenomanian-Turonian strata in the Southern Galala Plateau (Eastern Desert, Egypt) were used to identify major factors controlling their regional and…
The main stage of recovery after the end-Permian mass extinction: taxonomic rediversification and ecologic reorganization of marine level-bottom communities during the Middle Triassic
TLDR
The Early Triassic lag phase represents the time when the reduced species richness in the wake of the end-Permian mass extinction was insufficient for stimulating major diversifications, whereas the Anisian main diversification event started when self-accelerating processes became effective and stopped when niche-crowding prevented further diversification.
Elevated Cranial Sutural Complexity in Burrowing Dicynodonts
Relationships between the complexity of the cranial sutures and the inferred ecology of dicynodont synapsids are explored. Simple complexity indices based on degree of sutural interdigitation were…
Dynamics of the Largest Carbon Isotope Excursion During the Early Triassic Biotic Recovery
The dynamics of the carbon cycle across different timescales is crucial for understanding past and present global climate changes. Following the Permian–Triassic boundary mass extinction (PTBME), the…
Paleoclimate and sea level response to orbital forcing in the Middle Triassic of the eastern Tethys
Abstract The Middle Triassic is thought to have had a greenhouse paleoclimate with a few short humid phases. However, the timing of these humid events, and the extent to which orbital forcing…
Astronomically forced changes in chemical weathering and redox during the Anisian (Middle Triassic): Implications for marine ecosystem recovery following the end-Permian mass extinction
Abstract The timing and pattern of ecosystem recovery following the end-Permian mass extinction are still highly controversial, and a potential influence from orbital climate forcing is often not…

Olenekian (Early Triassic) bivalves from the Salt Range and Surghar Range, Pakistan
Based on newly collected material from the uppermost Smithian and lower to middle Spathian (Oleneki- an, Lower Triassic) of the Salt Range and Surghar Range (Pakistan), 15 bivalve species belonging…
Middle Triassic (Anisian, Bithynian) gastropods from North Dobrogea (Romania) and their significance for gastropod recovery from the end-Permian mass extinction event
TLDR
The Mahmudia fauna suggests that metazoan reefs recovered more slowly than benthic faunas, and sheds light on the pattern of ongoing recovery from the end-Permian mass extinction event.

LATEST TRIASSIC–EARLIEST JURASSIC BIVALVES OF THE GERMIG FORMATION FROM LANONGLA (TIBET, CHINA)
Abstract The Germig Formation of the Tethyan Himalaya of southern Tibet contains an exceptionally abundant bivalve fauna which has been found in association with choristoceratid and psiloceratid…
Bivalves from the Olenekian (Early Triassic) of south-western Utah: systematics and evolutionary significance
The recovery from the end-Permian mass extinction event was a key interval in the history of life, but few modern studies provide systematic data on benthic marine faunas from the epoch immediately…
Diversity, palaeoecology and systematics of a marine fossil assemblage from the Late Triassic Cassian Formation at Settsass Scharte, N Italy
TLDR
The present assemblage underlines the pronounced heterogeneity of the Cassian biota and is interpreted as an autochthonous soft bottom assemblages dominated by species that lived in low epifaunal to shallow infaunal habitats.
Oysters and oyster-like bivalves from the Middle Triassic Muschelkalk of the Germanic Basin
TLDR
It is demonstrated that N. speculostreum was invariably attached by its right valve, in contrast to an externally similar species from the Lower Muschelkalk Freudenstadt Formation that was exclusively cemented by its left valve, and thus represents the geologically oldest known oyster species.
Pinnidae (Bivalvia) from the Reuchenette Formation (Kimmeridgian, Upper Jurassic) of northwestern Switzerland
The shallow-marine carbonate deposits of the Reuchenette Formation (Kimmeridgian, Upper Jurassic) in northwestern Switzerland and adjacent France yield highly diverse bivalve associations, but only…
RHAETIAN (LATE TRIASSIC) MONOTIS (BIVALVIA: PECTINOIDA) FROM THE EASTERN NORTHERN CALCAREOUS ALPS (AUSTRIA) AND THE END-NORIAN CRISIS IN PELAGIC FAUNAS
Species of marine bivalves of the pectinoid genus Monotis provide useful biochronologic indices for the Late Triassic (middle Norian-earliest Rhaetian). We report the succession of Monotis at…
